Webb31 jan. 2024 · A NIST-built diffractometer, incorporating many advanced design features, was used to certify the lattice parameter of the LaB 6 powder. Both Type A, statistical, and Type B, systematic, uncertainties have been assigned to yield a certified value for the lattice parameter at 22.5 °C of a = 0.415 682 6 ± 0.000 008 nm (95% confidence). WebbThe primary particle-sizing calibration is conducted using NIST SRM 2806x suspensions with particle size distribution certified by the United States National Institute of Standards and Technology (NIST) for particle sizes 30 µm(c) and smaller, and using polystyrene latex spheres at larger sizes.
